I can see both sides of the argument, and in the end I kind of come down on the side of indifference.

In ESB, Boba Fett didn't do much really. He was smart enough to realize Han was still in the area and only hiding, but beyond that he only told Vader where they were going in time for Vader to get there first.

I can see the problem with a slapstick death, but more because it's slapstick--not because it cheapens Fett as a character.

...I suppose where I really come down on it is that I like the original theatrical versions of the OOT, and so for me the issue is more about whether arbitrary changes to the death of an obscure character are warranted when they do nothing to help the plot or else fix inconsistencies. That is to say, Fett's death can be changed, but only if it doesn't change the film to feel different than it did originally. For example, putting more AT-STs at the Battle of Hoth not only fixes inconsistencies, but it also makes sense. And yet it doesn't really change anything with regard to the story.

Unlike the prequels, I don't feel that the OOT needs improving or fixing in order to become good films. They're great the way they are. Ady can change Fett's death to something that might make more sense, but if he makes changes to the story, then I don't want it.
